Hey, so I got up to the same point as you in this door tutorial and I found out how to fix it.
I’m currently still learning UE4 so I apologise in advance if I’m using incorrect terms.
- Set the “Door End” Default like you have already done.
- Make sure the green lerp node and the blue set relative location nodes are unconnected.
- Right click on yellow new location pin within the blue set relative location node and select “Split struct pin”
- Connect the return value pin in the green lerp node to the new location z pin inside the blue Set Relative Location
- The axis value can be change in the the “Door End” default class
*Note you can connect multiple pins in each node just know that the values will be the same.
Version 4.20.1
Hope this helps,
Jeremy
